    Abstract: Provided is a laser having a multilayer reflector that suppresses the multimode operation. A vertical cavity surface emitting laser includes a first mirror, a cavity having an active layer, and a second mirror that are laminated. The second mirror is a multilayer reflector comprised of a first layer and a second layer that are alternately plurally laminated, the second layer having a refractive index higher than that of the first layer. At least one of the plural second layers has an oxidized confinement structure having an oxidized region and a non-oxidized region.

    Abstract: A surface-emitting laser has an active layer between a first distributed Bragg reflector and a second distributed Bragg reflector. The first distributed Bragg reflector is formed so as to have a resonant mode and a first longitudinal mode different from the resonant mode included in the reflectivity stop band and a second longitudinal mode different from the resonant mode and the first longitudinal mode excluded from the reflectivity stop band. Oscillation is suppressed in the first longitudinal mode and in the second longitudinal mode. As a result, the surface-emitting laser can oscillate in a single longitudinal mode, suppressing longitudinal mode hopping.
